Specification of Letters Patent.

Patented Oct. 28, 1913.

December 28, 1912. Serial No. 739,005.

To all whom it may concern Be it known that 1, MAX TOLTZ, a citizen of the United States, residing at St. Paul, in the count-yof Ramsey and State of Minnesota, have invented a new and useful Improvement in OreDocks, of which the following is a specification, this appllcation being a division of my application, Serial No. 622,498, filed April 21, 1911.

The object of this invention is to provide a dock structure of the character set forth in Patent N umber rosossr, granted to me on the 14th day of January, 1913, this application being a division of the subject matter thereof. 7

This invention involves the construction of dock claimed in said patent out of cementitious material whereby a monolithic structure is produced having great strength and endurance and meeting the needs required for quickly and effectively loading boats or other conveyances with iron ore, coal and other materials.

In the accompanying drawings forming part of this specification, Figure 1 is a sectional elevation of my invention; Fig. 2 is a plan partly in section, and Fig. 3 is a section on the line XX, Fig. 1.

In the above drawings 1 have illustrated a series of ore bins A supported on foundation B. Each of the bins A is fitted with an ore spout or chute C for the loading of vessels lying adjacent to the dock and a hoist D placed at the top of the bin to elevate the chute when not in use.

The foundation B of the dock on which the bin structure rests may be varied in form the drawing illustrating a concrete subfoundation 2 extending to any depth and carrying columns I made out of cementitious material on which rest the side walls 3 of the bins A. The columns I may be filled in with solid concrete transversely of the dock to brace the columns laterally. The foundation may be of any suitable form having the feature of a fixed surface adapted to the sup port and anchorage of the wall of the bin structures.

The bins A are built in pairs extending across the dock and series of pairs are built adjacent to each other upon the foundation to form the length of the dock. Each bin A considered apart from the adjacent bins consists of two side walls 3 roughly triangular in shape and connected by the bin front 4 made of concrete integral with the side walls and semicircular in shape.

Each bin has a floor 5 in the form of a slab integral with the side walls and slanting downfrom near the middle line of the dock to the bottom of the bin front, and raised from the lower edge 6 of the bin walls. The floor is formed with strengthening beams 7 and 8 below it. The back walls of the bins are produced by concrete girders 9 connected by the horizontal web 10 lying flush with the level of the surface of the dock structure. The walls of the bins form a girder structure integral with the adjacent parts of the bin.

The top of the deck of the dock is formed with stringer beams 11 extending horizontally of the deck and supported by the plates and columns of the bin walls with which they are integral and fitted to carry the rails 13 of the dock railroad tracks. These beams may also be used to support the decking 12 of the deck. The tracks are adapted to carry trains of cars loaded with ore, coal, etc, along the deck of the dock above the bins A where the cars may be dumped or unloaded in any suitable manner through openings 29 in the deck. Two lines of track extend along each side of the dock above the line of bins on that side of the dock. Any number of lines of track may be employed.

At the bottom of the bin where the bin floor meets the bin front an aperture 14: is provided in the bin front, fitted with a door 15 sliding vertically in suitable grooves on the bin front 4 and adapted to close the aperture in the bin front.

The parts of the concrete structure are suitably reinforced for strength. The side fwalls have horizontal rods 16 embedded therein to take up tensional stresses developed in the walls and to stiffen them against local pressures. The reinforcing rods extend into the front and are shown spaced closer together near the bottom of the bin where the pressure of the bin contents is greatest. The floor slab 5, strengthening beams 7 and 8, stringer beams 11 and girders 9 forming back walls have reinforcing rods 17, 18, 19 and 20 which respectively take up tensional stresses in the part in which they are embedded. Reinforcing rods 30 which are similar to the rods 16 are embedded vertically in the girder side walls 3 and are bent to extend horizontally through the floors 5. thus assisting in carrying the floor loads to the walls 3 and binding the walls 3 and floor 5 together, see Fig. 3. The girders forming the side walls have their lower portion suitably reinforced along their edges by rods 21 to take up stresses in the concrete.

A concrete structure 22 is shown connecting the tops of the columns of the foundation said structure being reinforced by rods 23. The side walls 3 may be widened at their lower portions as illustrated in Fig. 3 for the purpose of increasing their strength where the load is the greatest and economizmg in concrete material. The mode of reinforcing the concrete or constructing the parts out of armored concrete may be modified and changed in any manner generally known by those skilled in the art to which this invention relates. The use of non-reinforced concrete is also contemplated within the scope of my invention. The reinforcement shown is adapted to positively tie the entire dock structure together both laterally and longitudinally and serves to prevent cracking. The cement parts described are adapted to form a monolithic structure of great strength.

A chute 24 is placed below the aperture 1% in the bin front and the spout C is hinged to said chute and adapted to swing up clear of the boat or lower into the position indicated in Fig. 1 for loading the boat. The lower end of the spout has a bail connection 25 for a hoisting line 26 the latter being connected with a suitable hoist D placed at the level of the deck of the dock and operated by hand or power. The hoist rests on a platform E which extends outward from the bin, overhanging the bin front and allowing greater clear space on the deck of the dock and is support-ed by brackets 27 attached to the bin front. The platform E is surrounded by a handrail 28.

The load of ore or other material carried in the bin is principally carried by the floor 5 by which it is transmit-tedto' the floor beams 7 and 8 underneath the floor and also through the concrete floor and by said concrete beam connections to the concrete girders 3 which also form the bin walls. The floor of each bin and the floor load are carried by the bin walls the floor being hung therefrom. The other impressed loads of the bins are the deck and train loads which are relatively light in a loaded dock, and which are transmitted largely by the column structure to which they are first imparted, to the lower part of the bin walls which are freed from lateral stresses. The part of each wall to which this load is imparted has the general form of a cantaliver girder supported by the foundation column and having its greatest depth at that point where the loading is the greatest, from which it decreases in depth toward its end where the loading is lighter.

The floor load directly above the foundation column I is transmitted directly thereto and the loads to either side are carried by the cantaliver action of the girder wall. The bin is so placed upon the foundation columns that the center of gravity of the bin when full is directly over the foundation columns I. Variations in the loading and unloading of the bin together with the weight of moving trains at times moves the center of gravity of the bin from over the foundation resulting in a tendency to rotate the bin about its anchorage upon the foundation. This tendency is overcome by the connecting girders F which join the walls of the bin of a pair, producing in effect a continuous girder extending across the dock and resting upon the columns of the foundation. The balancing of the bin loads about the foundation supports permits economy of construction with effectiveness equal to that of a girder of a uniform depth.

The semi-cylindrical front wall of each bin by its shape reduces its pressure stresses to tensions and serves to reduce the tendency of ore or other materials packing in the bin resulting in arching when the bin is dumped. The side walls serve to support the floor loads of the bin and transmit them to the foundation of the dock. By incasing these parts in concrete a multiplicity of girder and trussed supports and other parts together with the additional bracing required are obviated or reduced and a monolithic structure is produced of great strength and rigidity capable of withstanding great strains and loads such as are produced by trains of cars unloading into the bins and of vessels bumping against the dock struc-' ture. Another important advantage is afforded by the use of concrete producing an absolutely fire proof structure requiring no insurance against loss caused by fire.

In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
